Module sim 

Core simulation engine for deterministic testing. Core simulation engine for deterministic testing.

This module provides the central SimWorld coordinator that manages time, event processing, and network simulation state.

Submodules

• world - Core SimWorld and WeakSimWorld types
• events - Event types and queue for scheduling
• state - Network state management (connections, partitions, clogs)
• wakers - Waker management for async coordination
• sleep - Sleep future for simulation time
• rng - Thread-local random number generation

Modules

A priority queue for scheduling events in chronological order.

ScheduledEvent

An event scheduled for execution at a specific simulation time.

SimWorld

The central simulation coordinator that manages time and event processing.

SleepFuture

Future that completes after a specified simulation time duration.

WeakSimWorld

A weak reference to a simulation world.

Enums

ConnectionStateChange

Functions

get_current_sim_seed

Get the current simulation seed.

reset_sim_rng

Reset the thread-local simulation RNG to a fresh state.

set_sim_seed

Set the seed for the thread-local simulation RNG.

sim_random

Generate a random value using the thread-local simulation RNG.

sim_random_f64

Generate a random f64 in the range [0.0, 1.0) using the simulation RNG.

sim_random_range
